I bought this inverter to run my home fridge during power outages. It works great. No problems starting and running the compressor. It even handled a 1/2" drill motor easily.
I picked this one for it's power and voltage display. It allows me to estimate the battery draw so I have an idea how long it will last. I also liked the USB power source, although I have not used that yet.
It does come with nice HEAVY power leads (with clips), although they are very short. Good enough to set right next to a battery and clamp on.
So far, no complaints or problems.

I have these in all 4 of my company's vans to run heavy duty continuous use machines. My old inverters would pop and I would have to turn them off and back on. If these surge it resets itself within less than a second and keeps on truckin. I had to install a solenoid for them to work correctly (my mechanic advised me to do that, I dont know the technicalities) because without the solenoid it wasn't drawing enough power. I have been very impressed with the quality and price of these and will continue to buy them.Best Deals for Cobra CPI1000 1000W 12V DC to 120V AC Power Inverter with USB Port
My first review of this product was not a kind one. I could not use a toaster or coffee pot with this device and chastised cobra for over stating the wattage capabilities. After many hours of work and upgrading to another bigger one with the same results, I wanted to rewrite my review. If you take this inverter or the bigger one, and put it right at the battery with the supplied clamps, it WILL deliver a strong output and make a pot of coffee with a normal toaster. Keep in mind a toaster and a coffee pot are pretty much a direct-short to a power supply since they are heating elements. There is no more difficult task for an inverter to do! Vacuum cleaners, all those things are easy compared to heating element type appliances. Anyway, back to installation. If you have the device RIGHT at the battery it will deliver as promised since there is a short wire and no voltage loss.BUT when I installed it under the seat of my RV with a top of the line amp install kit about 12 feet away, it did NOT deliver. It would beep and shut down. Even with the 100% copper wire, oxygen free stuff I used, it had voltage drop to make the inverter go below the magic level that makes it freak out. In my installation, I could NOT mount the inverter at the battery--there was not enough room. So long story short I put a second battery under the seat of the RV next to the inverter/ this battery only drives the inverter. Problem solved. works like a charm, but I would invest in the bigger one-if you can afford it. The voltage drop in the wire is very real issue. I am in the car electronics business and sell such things and it even amazed me and my co workers .
The bad thing to keep in mind, is that all of these converters have a cooling fan. You will hear this loud whirring noise while it runs. The fan has two speeds. If your car is running and it gets enough voltage the fan goes at low speed. BUT if your car is not running the fan is in high speed. Keep this in mind, you WILL hear this and it may make watching TV annoying. Install the inverter accordingly.
You do get what you pay for in inverters. If you were to step up to the more expensive brands of inverters that boast "sine wave" and "noise filtering" You will pay $400 or more and I bet they have less issue with voltage drop. But hey, you have to live within your budget.
